CORK-Cu'rrmemecmnn speeifee'ien ef Lettere" Patent No. sacs, dated July 8,1 1851.

To all wwm t mayconcem:

Be it known that I, VILLIAM KING, of

the city, county,`and State of New York, have invented an Improvement inMachines for Cut-tingCorks; and I dohereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed `drawings, making a part of this specification, in which- Figure I isa view in perspective. Fig. 2 is a section indetail and like letters refer to like parts. in boththe figures. i

The nature of my invention consists in such construction `of a machine for giving the cylindrical forinto bottle corks, as will enable the workman readily to adjust it` while actually cutting, to cut a perfectly formed cork of the largest size the square will admit. In all machines for this purpose hitherto in use the corks are cut to a uniform size, butin practice this is not found to be desirable, as from the peculiar nature of the material it is diflicult to provide squares of uniform size, and hence, where the machine must be set to cut a perfectly formed cork from squares of the smallest size, a loss of stock results onlall others. Y

My construction for this purpose is as follows. On a suitable frame work A I place a vertical shaft (b) in proper boxes (0, 0') having on the t-op a horizontal knife (E) which is a thin circular plate of steel strengthened by suitable disks (E' On the shaft is also a pulley (f) by meansofwhich rotary motion may be `ven.

Attached to the frame A, and perpendicularly below the edge of the knife, is a plate (a).to each end of which are affixed uprights (g, g) having on them guides (g g' A block (it) within these guides may be moved vertically when required by making the lower side of the block (71,) in the form of a double wedge, and the upper side of the plate (a') of the same form inverted; and placing between them wedges (z', operated by a shaft, (i) on which are right and left screws working through the wedges in a manner well known and `the whole of which is clearly shown in Fig. II.

On the top of the block I place a tea (le) Whieh is hinged et one end (lef) te on this bed is anadjustable head (m) supporting a mandrel (m') to which motion is given by a pulley The holder or chuck (0) by which the square is made to revolve is of the construction common for this purpose, and is xed on the end of the also another head (p) y moving on a slide (20') `and sustaining `a holder or center (0') capable of revolving, the axis of which must Vbe in the samelline as that of the mandrel (m'). To the head (p) a cord (r) is attached which passing over a sheave (r') to a treadle (t) serves tomove the head (p) upon its slide toward the head (m). `A spring (s.) is also attached to the opposite side of the head for the purpose of withdrawing it. i The operation of mymachine will be as follows. The bed (k) is first raised by turning the set screws (Z), to give the required conical form to the cork, the block (la.) is then adjusted to such distance below the edge of the knife as will bring the holders far enough below the knife to ac `commodate a square of the largest size among the lot to becut; rapid rotary motion is then given to the knife, and a comparatively slow motion to the chuck (0) in the directions` indicated. The workman now places with his left hand the smaller end of a square against the center (0') and with his foot presses the treadle bringing up the head (p) so that the piece of cork comes in contact with the chuck (0). `It is thus caused to revolve and with it now revolves the center `or holder (0'). If the piece should chance to be a small. one, and the square is not sufliciently cut away to give a perfectly formed cork, theworkman with his right hand turns the .shaft (2) by means of a crank, raising the block (it), and with it the holders, the cork still revolving, and thus the cutting may be continued as long as desired. By raising the foot from the treadle the head (p) will be no longer held; the spring (s) will then be permitted to draw it back, and the cork will drop out.

I produce the like results by equivalent mechanical means.

What I claim as of my own invention and desire to secure by Letters Patent is- The lifting block (h) susceptible of such adjustment with reference to the edge of the knife, While the machine is in motion that from squares of Varying sizes perfectly formed corks may be cut, of the largest size each square Will afford, the Whole being con- 10 structed and operating substantially in the mannerherein set forth.
